Error on Homepage when updated from 2.1 to 2.3

Hi,

I updated the test installation by uploading the new version via ftp. Admin is working fine, but home page is giving below error. I am not using any third party extension. Please advice.


Fatal error: Uncaught exception 'Exception' with message 'Error: Could not load model total!' in /home/rbhomupx/public_html/testcart/system/engine/loader.php:169 Stack trace: #0 [internal function]: Loader->{closure}(Array, Array) #1 /home/rbhomupx/public_html/testcart/system/engine/proxy.php(25): call_user_func_array(Object(Closure), Array) #2 /home/rbhomupx/public_html/testcart/catalog/controller/common/cart.php(37): Proxy->__call('getTotal', Array) #3 /home/rbhomupx/public_html/testcart/catalog/controller/common/cart.php(37): Proxy->getTotal(Array) #4 [internal function]: ControllerCommonCart->index(Array) #5 /home/rbhomupx/public_html/testcart/system/engine/action.php(51): call_user_func_array(Array, Array) #6 /home/rbhomupx/public_html/testcart/system/engine/loader.php(24): Action->execute(Object(Registry), Array) #7 /home/rbhomupx/public_html/testcart/catalog/controller/common/header.php(129): Loader->controller('common/cart') #8 [internal function]: ControllerCommonHeader->index(Array) #9 /home/rbhomupx/public_html in /home/rbhomupx/public_html/testcart/system/engine/loader.php on line 169
